Application filed September 16, 1921. Serial No. 501,059`

To all. whom 'it may concern:

y Be it known that I, BERNARD HAjUsMAN,

a citizen of `the United States, residingin the borough of Manhattan ofl the( city' of 5 New York, kin, .the State? of New York, have `invented certain new and usefullmprova Inents in Metal Windows,yof which the following is* a specification, reference` being had to the accompanying drawings, foriningapart hereof. A d

This invention Vrelates .to the construction of metal windows and is concerned particularlyl with kthe yvertical sections or sides of the` frames and theicounterbalancing of the sashes. `It is generally.considereddesirable that the vertical axis of eachv counterbalancing weight be lin the -plane of the sash to which it is connected.V Window vsashes of wood yor of hollow metal 'construction are usually of considerable thickness and the sides. of the frames are correspondingly of so much thickness that thereisA generally enough room to hang readilyr the ordinary' counterbalancing weights, approximately square in cross'section, with their vertical axes in the planes of the respective sashes. When, however, thesashes are made of solid metal, they are frequently. so thin that the sash weights, sufficiently heavy, to counterbalance the sashes, cannot be placed with their axes in the planes of the sashes. In

one type of construction it has been pro-V posed to let the two sash weights at each side have a cross section other than square, and place the weight with its longest diameter substantially in the planeof the corresponding sash, butk this requires frequent-- ly special weights and special construction with an undue depth, which latter tends to reduce the light area of1 the windown lIn another construction'L it has been proposed to .place the `sash pulley with its axis oblique to the plane of the sash, which in practical 4operation `will prove objectionable for ni'anywreasons. One object of the invention is to provideineans whereby these difficulties can `be overcome and in accordance therewith one of the sashes (upper or lower), or, if necessary, each of the sashes, isprovided` at each side with an arm which projects frein ,the plane of the sash toward and beyond' the plane of the vertical axes-of the two corresponding sash weights,

so that the sash chain can be connected to the sashV in the plane of` vertical laxes of the sash weights. The axis of rotation of the sash pulley is at rightangles to the plane of thesash and to the plane of the vertical :axes of the sash weights and there is consequently no twisting and no friction in the inoveinent vrof Ithe chain of the sash, which could impede its free travel. A further purpose of the 'invention is to provide for the complete enclosure of the sash chain, so that no part of'itA shall be visible. Still another object of the invention Aislto provide for the side vframe a stati1 and stop bead, independent of the frame,which can be inade ofheavy nietal and therefore be relied upon to stiften the frame without requiring like heavy metal to be used in kthe construction of the fraine and can alsorbe made of galvanized stock, to prevent rust, while the frame can be niade of black iron or steel. The invention will he explained more fully hereinafter with reference to the accompanying drawing ,inV

which it is illustrated and in which- Figure 1 is a view in elevation of so vmuch of a window frame and sash as is necessary to enable the invention to be understood, the sash weight, chain and pulley being indicated in dotted lines.

Figure 2 is a view in horizontal section on the plane indicated by the broken line 22 ofFigure 1.

Figure 3 is a detail` view in perspective illustrating the connection between the chain and the sash.

Inthe embodiment of the invention illustrated in the drawing, each of the two hollow vertical frames (only one of vwhichis necessary to be shown) is forined of two sheets of nietal a and b. Sheet a is a flat sheet and forms that portion of the vertical frame which is adjacent to the building wall. The two sheets a and are united in any suitable manner, as indicated at a. The sheet ZJ preferably forms three sides of the vertical frame and is iniperforate or so formed, in conjunction with other parts to be inentioned, as to avoid vertical openings through the rnetal, For this purpose it is formed, on

the side adjacent the sashes, with a recess Z1 for co-operation with the upper sash as hereinafter described, and with ay recess b2 for co-operation with the lower sash. As the sheet is imperliorate, that is, is not slotted vertically for co-operation with either ot the sashes, comparatively light metal can be used in its construction, especially if its stillness at the exposed outer edge is increased Aby the combined staff and stop bead c of L- shape which may be lnade of heavier metal and secured to the sheet Z) by any suitable mea-ns, as by screws, one of which is indicated at c. The outer portion 02, which is turned back upon itself as indicated, forms a still statil bead, while the inner' edge c overlaps the recess L formed in the sheet L and forms a guide cd for the co-operating portion of the upper sash. This combined sta'll and stop bead, which is exposed to the weather, can also be made of galvanized or other anti-rusting stock, to resist rust` while the frame can be made oit black iron or steel. At its inner edge the vertical frame b, also stili'ened by the hollow stop bead (l, which may be secured to the sheet l) by any suitable means, as by screws (Z, being seated in the recess b2. rlhis stop bead forms a guideway (Z2 for co-operation with the lower sash and it also forms a complete enclosure for the sash chain, which is thus desirably concealed from view and yet will also admitready recess in case of breakage of chain, etc.

The vertical frame Z) receives the sash weights e, e for each sash both of which may be of the usual form, being substantially square in cross section, while provision is made, as now described, whereby each sash chain c is connected to the corresponding` sash in the plane of the two sash weights on opposite sides of the window, parallel with the sash itself and the axis of the sash pulley7 e2 remains at right angles to the plane of the window. Each of the sashes may be formed as usual in windows of the character indicated, having an inner plate f and an outer plate f2. These two plates receive the glass g between them and are secured together by screws or rivets f3, while the'edge or' one oi. the plates, as the plate f2, is extended toward the frame, as at f4, to

enter the guideway 04 or d2 and guide the' sash in its up and down movements. To such extended edge or' the as by slotting and welding, an arm f5 which is extended laterally from the member f2, f4, across the plane of the vertical axes of the two sash weights which are to be connected to the corresponding sash. The relative lengths and positions of the arms f5 of the two sashes will be determined by the cross section of the side frame and the relations of the sashes to the side frame. In the arrangement shown, the arm f5 of the upper sash is secured,

sash is preferably turned outwardly and is quite short. It moves in the recess lormed therefor and it and the chain are protected by the overlapping edge of the combined stall' and stop bead c.

longer and is turned inwardly, moving within the hollow stop bead d. By this arrangement both sash weights e, at both sides or' the window, are of the usual form, which might be either approximately square in cross section and each is connected to the corresponding sash at a point which is in the plane of the vertical axes of the two sash weights at opposite sides of the corresponding sash, while the axis of rotation ot the sash pulley is at right angles to the pla ne of the sash. It will be understoodv that an opening or pocket is provided for on the inner part. of each vertical member of the window frame, directly back of the inner stop bead and thus covered by it, for the yinsertion of the weights into the window box and tor their ready access, when required.

lt will be understood that details of construction and arrangement can be varied to suit diliierent conditions of use and that the invention, except as pointed out in the claims, is not limited to the precise construction shown and described herein,

I claim as my invention:

1. In a metal window, the combination ot a hollow vertical trame member having its side adjacent to the sash 'imperfo'ate and formed with a recess and a combined stati and stop bead secured to the frame and overlapping the recess to form a guideway for the sash and a channel for the sash chain.

2. In a metal window, the combination of a hollow metal vertical frame member having its side adjacent to the sash impertorate and recessed and a hollow metal stop bead secured to said :trame member in said recess to form a guideway for the sash and a channel for the sash chain.

3. In a metal window, the combination of a hollow vertical frame member, a sash. having an extended portion to co-operate with said frame member in the movement of the sash, a sash pulley having its axis at right angles to the plane of the window, a sash weightand chain the weight being thicker than the sash and having its axis ol'lset from the plane of the sash, and an arm extended troni the extended portion of the sash in a direction at right angles to the plane oi the sash to the plane of the vertical axis ot' the sash weight, parallel with the sash in a vertical plane and having the sash chain connected thereto.

el. In a metal window, the combination o't' a hollow metal vertical frame member having its side adjacent the sash, imperforate and iliornied with a vertical recess, a sash having a portion extended into such recess The arm f5 olf the .lower sash, in the arrangement shown, 1s

to (3o-operate therewith in the movements 0f the sash, a sash weight and chain and an arm extended from the extended portion of the sash in a direction at right angles to the plane of the sash to the plane of the vertical axis of the sash Weight parallel with the sash and having the sash chain connected thereto7 and a stop bead secured to said frame member n operative relation with the recess and forming therewith a guide for the 10 sash and a Channel for the laterally projeetng arm and the Chain.
